Easy to use. Tall and thin for space saving

This was really easy to set up. I like how you can leave the water chamber in it a just pour in. It works really well to bring up the humidity in my large living room. I like that it has a cool and hot setting. It’s not super large and fits in a corner nicely.

Great addition for the house

We live in southwest Oklahoma where the climate is semi arid. When we run the furnace and the fireplace it sucks the moisture out of the house. We have been running the humidifier for a couple of weeks and we can already notice a difference. We breathe easier and the is less static in the house. It is able to keep the house at 50% humidity easily.

Great Features, Minor Flaws

The PureGuardian 1.5 Gal. Warm and Cool Mist Ultrasonic Humidifier is an impressive device that offers a blend of functionality and convenience. Its 1.5-gallon tank is a standout feature, allowing the humidifier to run for two to three nights without needing a refill, even when used for approximately nine hours each night. The humidifier offers versatile features, including three levels of humidification, UV light to sanitize water, and a soothing LED light that can either cycle through colors or remain fixed on one. The scent diffusion option adds a nice touch, although it’s slightly disappointing that essential oils cannot be added directly to the water. Overall, the humidifier provides excellent performance and thoughtful features, making it a solid choice for maintaining comfortable indoor air quality. On the downside, the humidifier does have some minor inconveniences. While the large tank is a benefit for extended use, it can be unwieldy to handle when full, making it tricky to load back onto the base. Additionally, the bright indicator light on the front can be distracting in an otherwise dark room, especially for light-sensitive sleepers. It’s unclear if this can be adjusted, and I plan to revisit the manual to check for solutions. Despite these drawbacks, the PureGuardian humidifier remains a reliable option that effectively balances functionality with ease of use.

leaks between tank and base

Just filled the tank for the first time and it leaks between the tank and the base. Not sure how it would not leak.

Useful product to keep around house

This is a mighty and compact humidifier that works great and has a few different settings. Very convenient and easy to use. Recommend the colds and flu are setting in this time of year when everyone is ill.

Good quality

I love the fine mist and that you can set the humidity %. I don't even hear it running.

No heated mist

I have several cool mist humidifiers in my home. I bought this, and shelled out the extra money specifically for the warm mist function for my bedroom so that I'm not alternating between 2 separate machines. There is absolutely no detectable temperature difference between the warm and cool settings. It works just fine otherwise but I could've just kept my $30 humidifier.
